      @manilx The incorrect backup size warning is a known issue that we will investigate soon 🙂

            @rtjdamen We are investigating it as well 🙂

            For the XO backend team, the next few months are focused on stabilization, bug fixes and maintenance 🙂

              @julien-f @florent @olivierlambert I'm using XO source master (commit c5f6b). Running Continuous Replication with NBD+CBT and Purge Snapshot. With a single (one) NBD connection on the backup job, things work correctly. With two NBD connections I see some Orphan VDIs left almost every time after the backup job runs. They are different ones each time.

                I noticed when migrating some VDIs with CBT enabled from one NFS SR another that the CBT only snapshots are left behind. Perhaps this is why a full backup seems to be required after a storage migration?

                  @flakpyro i know from our other backup software we use that migrating cbt enabled vdi’s is not supported on xen, when u migrate between sr it will disable cbt on that vdi. This is causing a new full. This is by design

                    @rtjdamen Makes sense, it would be nice is XOA cleaned up these small CBT snapshots though after a migration from one SR to another.

                      @flakpyro indeed, sounds like a bug. It should delete the snapshot, disable cbt and then migrate to the other sr.

                        I've been out of life for a while.
                        is it any known problem with CBT file restore?

                                      Hi, I am running from the sources and I'm almost up to date (991b4) . Can anyone please tell me what this means "Error: can't create a stream from a metadata VDI, fall back to a base". Restarting the backup results in a full backup rather than an incremental.
                                      Thanks.

                                          Getting coalesce stuck on one SR, NFS share.
                                          After running a Continuous Replication job. When I use an internal SSD as the target this does not happen.

                                            Because you are writing faster in the VM than the garbage collector can merge/coalesce.

                                            You could try to change the leaf coalesce timeout value to see if it's better.
